I have two of these bad boy's. one is powering 4 alpine 15" type R in a 06 dodge ram quad cab and it hitting 156.8 db. @ 30 hertz. you need a upgrade mechman alternator and at least 4 extra batteries. warning anything below 12 volts will kill this amp. do not buy this amp and run it an a factor alternator, it will die. Very good, durable, and easy to install. Use at least 1/0 cable for power.
